drm/ttm: Clear the ghost cpu_writers flag on ttm_buffer_object_transfer.

2010-12-09T21:26:52Z

commit 0fbecd400dd0a82d465b3086f209681e8c54cb0f upstream. It makes sense for a BO to move after a process has requested exclusive RW access on it (e.g. because the BO used to be located in unmappable VRAM and we intercepted the CPU access from the fault handler). If we let the ghost object inherit cpu_writers from the original object, ttm_bo_release_list() will raise a kernel BUG when the ghost object is destroyed. This can be reproduced with the nouveau driver on nv5x.

drm/radeon/kms: fix coherency issues on AGP cards.

2009-11-03T23:53:14Z

When we are evicting from VRAM->RAM we allocate the ttm object, but we don't set the caching policy on it before blitting into it. This means on AGP we end up blitting into cached pages, and the CPU later flushes out on top of them. This was mostly seen as font corruption. The other question is why we don't evict VRAM->GTT in a lot of cases, this would save us some cache transitions since a lot of objects that are evicted from VRAM will probably end up being pulled back in a few operations later, and evicting them to system memory involves 2 unnecessary cache transitions.
